Plan to share IPD

Yes

IPD plan description

Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal Vivli.org. All requests will be evaluated as per the AZ disclosure commitment: https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure. Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared. AstraZeneca will meet or exceed data availability as per the commitments made to the EFPIA PhRMA Data Sharing Principles. When a request has been approved AstraZeneca will provide access to the anonymized individual patient-level data via secure research environment https://vivli.org/. Signed Data Usage Agreement (non-negotiable contract for data accessors) must be in place before accessing requested information.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 4

1. ≥ 18 years of age at the time of signing the ICF
2. History of clinical ASCVD or at risk for a first ASCVD event: (a) Clinical ASCVD is defined as MI, stable or unstable angina, coronary or other arterial revascularisation, ischaemic stroke, or peripheral artery disease. (b) A participant is considered at risk for a first ASCVD event if the participant has one or more of the following conditions: atherosclerotic vascular disease (≥ 50% stenosis in ≥ 2 coronary artery territories or in ≥ 2 vascular beds [coronary, carotid, lower extremity], diagnosed by any imaging modality), diabetes mellitus, hypertension, cigarette smoking, chronic kidney disease (moderate to severe stage), or obesity. Investigators can also use the ACC/AHA or ESC or other relevant national clinical guidelines for risk assessment to identify participants with at least moderate risk for ASCVD.
3. Fasting serum LDL-C by central laboratory at screening as follows: LDL-C ≥ 55 mg/dL (≥ 1.4 mmol/L) in participants with clinical ASCVD; or ≥ 70 mg/dL (≥ 1.8 mmol/L) in participants without clinical ASCVD but at risk for a first ASCVD event
4. Participants should receive a background lipid lowering regimen anticipated to achieve at least a ~50% reduction in LDL-C. Except in cases of intolerance, the regimen should include a high-intensity statin therapy or lower intensity statin therapy in combination with an oral agent with proven outcome benefit (eg, ezetimibe and/or bempedoic acid). Thus, the background lipid-lowering therapy must consist of one of the following: − A high-intensity LDL lowering regimen (i) A high intensity statin regimen, as defined by country specific guidelines OR: (ii) A lower intensity statin regimen in combination with ezetimibe and/or bempedoic acid OR: − A maximum tolerated statin regimen - Oral combination therapy with ezetimibe and/or bempedoic acid is strongly recommended. Participants must achieve a stable background lipid-lowering therapy > 28 days before screening.

Exclusion criteria 7

1. Homozygous familial hypercholesterolaemia, known diagnosis of HeFH, LDL apheresis or plasma apheresis within 12 months prior to screening, or any other underlying known disease or condition that may interfere with interpretation of the clinical study results as judged by the Investigator.
2. Any of the following laboratory values at screening: Calculated eGFR < 15 mL/min/1.73 m^2 (CKD-EPI formula; Delgado et al 2022, Inker et al 2021) AST or ALT > 3 × ULN TBL > 2 × ULN (except for patients with Gilberts syndrome, where TBL 3 × ULN is acceptable provided direct bilirubin < 1.5 × ULN) Fasting triglycerides ≥ 400 mg/dL (≥ 4.52 mmol/L) Creatine Kinase > 5X ULN Urine albumin to creatinine ratio ≥ 500 mg/g
3. Uncontrolled type 2 diabetes mellitus defined as HbA1c ≥ 9.5% at screening
4. Inadequately treated hypothyroidism defined as TSH > 1.5 ULN at screening or participants whose thyroid replacement therapy was initiated or modified within the last 3 months prior to screening
5. Use of mipomersen or lomitapide (cholesterol-lowering medications) within 12 months prior to screening or planned use during the study
6. Use of gemfibrozil within 1 week prior to screening or planned use during the study
7. Use of PCSK-9 inhibitors: evolocumab/alirocumab within 12 weeks of the screening visit or planned use during the study or inclisiran within 18 months of the screening visit or planned use during the study. Any other approved PCSK-9 inhibitor use within 5 half lives prior to the screening visit or planned use during the study.
